Question

What does g(31415927) return, for the following function definition? def g(x): (q,d) = (1,0) while q <= x: (q,d) = (q*10,d+1) return(d)

Answer 1

"Answer is 25

the while loop will run 25 times

as 31415927 / 2**24 =1.8...  which is > 1

so for last time it will go

for 2**25 , d will be incremented 24+1=25

then it becomes less than 1

condition becomes false... while loop terminates

-->the no. of times x is divided by 2 & remains >1

the d will be incremented by 1"

Answer 2

Answer is 25

The while loop will run 25 times  

As 31415927 / 2**24 =1.8...  which is > 1

So for last time it will go  

For 2**25 , d will be incremented 24+1=25  

Then it becomes less than 1  

Condition becomes false... while loop terminates

-->the no. of times x is divided by 2 & remains >1

The d will be incremented by 1.
